Re: Galaxy S models

US GSM/WCDMA networks have never supported 3G video calling. Europe deployed 3G first - a long time ago - and video calling along with it. It was a flop. So the US networks have never supported it. Therefore all US versions of WCDMA phones omit the front-facing camera, because you can't do anything with it. There's nothing special about the Galaxy S not having a front camera in its US version. It's about the 150th example of that happening.

Only extremely recently - since Apple debuted FaceTime - has there been any interest in that feature in the US.

But anyway, you can't blame Samsung - or really the US carriers - for leaving out the front-facing camera. Data from Europe showed people almost never used that feature when they had it.

As for processor, no, I'm 99% sure the US versions have the same processor setup as the Euro version.

Each country has its own weird standards for mobile TV. That has nothing to do with the phone and everything to do with what the FCC and carriers support with regard to mobile TV. MediaFLO here in the US hasn't been very successful, so again, the data seems to show that people don't actually use that feature when they have it.
